citizen of the United States', residing in the city and vcounty of SanFrancisco and State of California,have invented-,new and usefulImprovements in Punct'u're-Proof T.re-

Lining, of which the following is a specifl-v cation. i A

This invention relates to a puncture-proof tire lining. I j

One of the objects of the present invention is toprovide a simple,substantial, cheaply manufactured puncture and blow-out proof lining,constructed of flexible metal, chain mail fabric for -pneumatic tires,vwhich -is adapted tov be vinserted between the inner x tubel and themain casing; there being.v -in the .1Cadw ay, yet' stubbornly resstspuncture. It also relieves the outer casing from theli'abilityto'blowfouts.v

usuallyprovided a secondary l'ning to prevent the chain fabric frominjuring either -the inner tube or the casing.

Another object of the invention is to provide means for securing theflexible. metaltire lining in position when the tire is inflated. j

Further objects will hereinafter appeal'.

-T'he invention consists of the parts and thelconstructio'n andcombination of parts as hereinafter mere full described and claimed,having reference to the accompanyingj'drawings, in whiclrl l Figure 1 isa cross section of a pneumatic tire, she-wing the application of theinvention.

Having thus descr bed my invention, whatI claim and desire to secure byLetters Patent isv i j 'In combination lwith awheel rim, an mnel" tubeand an outer casing having spaced' and a metal fabric lining connectedat its Y sides to the peripheral portions of the rings and disposedbetween the inner tube and casing, the free inner edgcsofsaid beads"abutting the outer faces cf saidrngs, said rings being of relativelygreat width so as to pro-vide wide walls against lwhich the inner tubemay exert pressure to 'effect'posi-- vtive outward movement cf thebea-ds upon inflation of the inner tube.
